Let’s be real. You’ve seen the photos. You’re scrolling through Instagram or a dermatologist’s gallery, and you see those side-by-side shots of stretch marks before and after treatments. In the first photo, the marks are deep, angry red, or maybe stark, shimmering white. In the second, they’re basically invisible. It looks like magic. But if you’ve actually tried a $60 "miracle cream" from an ad and seen zero results, you already know the truth is a bit more complicated than a filtered JPEG.
Stretch marks, or striae distensae if you want to get clinical, are actually scars. That’s the first thing people get wrong. They aren't just on the surface. They are structural tears in the dermal layer of your skin. When your body grows faster than your skin’s collagen can keep up—think puberty, pregnancy, or rapid muscle gain—the elastic fibers literally snap.
Why your "before" looks different than theirs
Most people looking for stretch marks before and after results are really looking for hope. But your starting point dictates your finish line. Fresh marks, which doctors call striae rubra, are red or purple. They’re still vascular. This is actually good news because it means there’s blood flow. If your marks are in this stage, lasers like the Pulsed Dye Laser (PDL) can work wonders. They target the hemoglobin and can actually shrink the vessels, fading the redness significantly.
Then you have the old ones. Striae alba. These are the white, silvery, depressed lines that have been there for years. They’ve lost their pigment. They’ve lost their elasticity. Honestly, getting these to "disappear" is nearly impossible without heavy-duty intervention. You aren't just changing the color; you’re trying to rebuild a sunken foundation. It’s like trying to fix a pothole in the road—you can’t just paint over it; you have to fill it in.

The heavy hitters: What actually changes the "after"
If you're looking for real-deal changes, over-the-counter stuff usually isn't it. Retinoids are the one exception. Tretinoin (Retin-A) has some solid backing in clinical studies, specifically for newer marks. It works by prompting cell turnover and encouraging collagen production. But you can't use it if you're pregnant or nursing, which is a huge bummer since that's when most people get stretch marks in the first place.
Microneedling has become the gold standard for many. It sounds terrifying. You’re essentially taking a device with tiny needles and creating controlled micro-injuries in the skin. Your brain goes "Oh no, we're hurt!" and floods the area with collagen and elastin to repair the site. In stretch marks before and after clinical trials, patients often see a 20% to 50% improvement in texture after four or five sessions. It’s not an overnight fix. It's a slow burn.
- Fractional CO2 Lasers: These are the big guns. They poke microscopic holes in the skin with light energy. It hurts. It’s expensive. But for deep, white marks, it’s one of the few things that can actually change the depth of the scar.
- Radiofrequency (RF) Microneedling: This is like regular microneedling but with heat. Devices like Morpheus8 or Vivace send energy deep into the dermis. This heat causes the skin to contract. It’s great for that "crinkly" tissue-paper texture that often comes with older marks.
- Platelet-Rich Plasma (PRP): Some clinics do "Vampire" treatments for stretch marks. They take your own blood, spin it down to get the growth factors, and needle it back in. It sounds like sci-fi, but the growth factors can speed up the healing process.
The myth of the miracle oil
Bio-Oil. Cocoa butter. Shea butter. We've all been told to slather these on. A study published in the British Journal of Dermatology looked at various topicals and found that most of them didn't do much to prevent or treat marks compared to a placebo. Hydrating the skin makes it feel better and might help with the itching as the skin stretches, but it’s not reaching the dermis where the tear actually is.

Does that mean you shouldn't use them? No. Keeping the skin barrier healthy is always a win. Just don't expect a $15 tub of cocoa butter to perform like a $3,000 laser series. It’s about managing expectations. The stretch marks before and after photos used to sell these creams are often misleading, lit differently, or involve people who just happen to have "good" genetics for healing.
Let's talk about the "tuck"
Sometimes, no amount of needles or lasers will fix the problem. This is especially true after pregnancy or massive weight loss where there is also redundant, loose skin. In these cases, the "after" people want usually comes from a tummy tuck (abdominoplasty). Surgeons literally cut away the skin where the stretch marks are located. If the marks are below the belly button, they’re gone. It’s the only way to "remove" them entirely. Everything else is just "fading" them.
Real expectations for your skin
You have to look at the texture. If you run your finger over the mark and it feels like a divot, you’re looking at volume loss. Lasers and needles help fill that divot. If it’s just a color issue, time is actually your best friend. Most red marks will eventually turn white on their own, even if you do nothing.

The psychology of this matters too. We’re bombarded with airbrushed images. Even "body positive" influencers sometimes use specific lighting to hide texture. When you see a stretch marks before and after photo that looks too good to be true, look at the pores. If you can’t see skin pores in the "after" photo, it’s been blurred. Real healing still looks like skin. It might be smoother, the color might match better, but the history of your body is still there.
What to do next if you want results
If you’re serious about changing the appearance of your skin, stop buying random creams. It’s a waste of money. Instead, take these specific steps to move from your "before" to a better "after."
- Get a consult with a board-certified dermatologist. Not an aesthetician at a day spa, but a doctor who understands scarring. Ask specifically about the difference between vascular lasers and resurfacing lasers.
- Start a prescription retinoid. If you aren't pregnant or nursing, Tretinoin is the most evidence-based topical you can use. It takes six months to see a difference, so be patient.
- Prioritize sun protection. This is huge. UV rays break down collagen. If you expose your stretch marks to the sun, the scarred tissue will often tan differently or become even more damaged, making the "after" look much worse. Use SPF 50 on those areas if they’re exposed.
- Hydrate from the inside. It sounds cliché, but skin elasticity relies on systemic hydration. Supplements like hydrolyzed collagen peptides have some (though debated) evidence for improving skin density over time.
- Set a budget. Lasers usually require 3-6 sessions spaced a month apart. It’s a commitment. If you can only afford one session, you’re better off spending that money on high-quality skincare and acceptance, because one session rarely does the trick.
Ultimately, the goal isn't necessarily "perfection." It’s improvement. Most medical treatments aim for a 50% to 70% improvement in the appearance of the marks. In the world of stretch marks before and after, that's a massive success. Your skin is a living organ, not a piece of fabric. It heals at its own pace, and while we can nudge it along with modern tech, a little bit of texture is just part of being a human being.
